While visiting this gorgeous post I thought myself what's the origin of this beautiful wreaths? after a little research I find out that originally, the circlet was called a "diadem" and took the form of fabric headbands which were sometimes adorned with jewels. Beginning in 776 B.C., wreaths made of laurel leaves were used to crown victors of Olympic Games. Later, when the Games began to move to different cities, each host city would award head garlands made of branches of local trees. Exactly when the transition from head ornament to wall decoration occurred is unclear. It is likely that celebration attendees simply hung the leafy headbands on their walls as souvenirs.
